Personal firewall programs such as BlackICE, Norton Internet Security, Sygate Personal Firewall, Tiny Personal Firewall, or ZoneAlarm protect you computer and your network from access by other people on the Internet. However, if the firewall is not configured correctly, it can do its job too well, preventing access by you to your own computers, as well.<\/p>\n
The only\u00a0<\/i>way to be sure that a firewall isn\u2019t causing your network problems is to completely remove it while troubleshooting. If that solves the problems, consult the firewall program\u2019s documentation for how to configure it to allow normal LAN access while protecting your network against outside access.<\/p>\n
Here\u2019s how to do it, with examples showing how to remove ZoneAlarm Version 2.6 from Windows XP. The steps should be similar for other firewalls:<\/p>\n
<\/p>\n
1. Disable the firewall. For ZoneAlarm, right-click the system tray icon and select\u00a0Shutdown ZoneAlarm<\/b>.<\/p>\n
<\/p>\n
2. Un-install the firewall, using the procedure provided by the manufacturer. This procedure is usually available in\u00a0Control Panel<\/b>\u00a0|\u00a0Add or Remove Programs<\/b>. Click the program name and then click\u00a0Change\/Remove<\/b>.<\/p>\n
3. Reboot the computer.<\/p>\n
4. Disable any remnants of the firewall:<\/p>\n
<\/p>\n
a) Click\u00a0Start\u00a0<\/b>|\u00a0Run<\/b>, type\u00a0msconfig<\/b>\u00a0<\/i>in the box, and click\u00a0<\/i>OK<\/b>.<\/p>\n
\n <\/p>\nb) Click the\u00a0Startup<\/b>\u00a0tab and un-check the box next to any remaining items related to the un-installed firewall.<\/p>\n
c) Click\u00a0Apply\u00a0<\/b>and\u00a0Close<\/b>\u00a0to exit.<\/p><\/blockquote>\n
5. Reboot the computer.<\/p><\/blockquote>\n
Don\u2019t re-install the firewall until you\u2019ve fixed the network problems.<\/p>\n
If you\u2019re concerned about other Internet users accessing your network while the firewall is removed, disable your Internet connection.<\/p>\n
